"Failed" during install/tests of stdlib (0.7.0) on ubuntu 22.04

Help stdlib
1

I’m trying to install stdlib on Ubuntu22.04 (on Windows-WSL).

I have cloned stdlib and uses v0.7.0.

I have followed the README and I am almost OK except I have a few “Failed” appearing during the install/test process, reported below through 2 questions.

FIRST question

After “cmake –build build”, i have the “Failed” message below. Is it important (and maybe related to the tests failure in SECOND question)

On -DCMAKE_BUILD_TYPE=NoConfig
– The Fortran compiler identification is GNU 11.4.0
– Detecting Fortran compiler ABI info
– Detecting Fortran compiler ABI info - done
– Check for working Fortran compiler: /usr/bin/f95 - skipped
– Performing Test WITH_CBOOL
– Performing Test WITH_CBOOL - Success
– Performing Test WITH_QP
– Performing Test WITH_QP - Success
– Performing Test WITH_XDP
– Performing Test WITH_XDP - Success
– Performing Test f18errorstop
– Performing Test f18errorstop - Failed

SECOND question :

After ctest --test-dir build/test, I get 3 Failed tests (see below). I would prefer no “Failed”! Do you observe the same behavior (ubuntu20.04 + stdlib tag 0.7.0)?

95% tests passed, 3 tests failed out of 64

Label Time Summary:
quadruple_precision = 0.39 sec*proc (2 tests)

Total Test time (real) = 19.08 sec

The following tests FAILED:
35 - mean (Failed)
52 - string_to_number (Failed)
56 - simps (Failed)
Errors while running CTest

This in itself is not an issue. In CMake there are checks to see if the compiler supports or not the error stop syntax. Within stdlib there two options of implementation to manage errors to enable support by compiler version which didn’t yet support this 2018 syntax.

Are you using Ubuntu 22 or 20 ? which compiler and which version are you using?

Actually, it is ubuntu22.04 with native gcc11.4.0 (and I use v0.7.0 of stdlib).

(FYI: I have installed inteloneapi 25.2 and everything is OK - no test fail.)

Do you have also the same 3 test failures on a similar configuration?

Couldn’t say, I work directly with the master branch and there have been many many fixes since the 0.7.0 upto the most recent 0.8.1. But I do build it on Windows and Linux with intel and gnu compilers and I don’t see any of those errors you mention with the recent versions.

Try upgrading to gfortran-13

sudo apt-add-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install gcc-13 gfortran-13 g+±13

you have to reference these using version extension

ie gfortran-13 not just gfortran.

see Installing GCC13 on Ubuntu 22.04

gcc 11 is very old.

7 tests fail (out of 86) with v0.8.1 on my configuration (WSL Ubuntu 22.04 (gcc11.4) + stdlig v0.8.1)

The following tests FAILED:
15 - intrinsics (Failed)
31 - linalg_pseudoinverse (Failed)
40 - linalg_solve_iterative (SEGFAULT)
44 - blas_lapack (Failed)
53 - mean (Failed)
70 - string_to_number (Failed)
78 - simps (Failed)

As README.md of stdlib says that GCC11 should be a supported compiler, I think that this feedback with gcc11.4 can be interesting for stdlib developers.

@both : many thanks for your replies
